green from the rocks although the small 

 white blotches of sand are usually the first 

 to attract the attention. Of course, the 

 preceding remarks apply to clear water and 

 will not hold good where the water is con- 

 tinually agitated and clouded by mud or 

 refuse. Swirling water usually indicates a 

 shoal or some submerged obstruction or 

 may be the result of a divergence of 

 current. 



When ready to cast off from the mooring, 

 haul in the slack on the dinghy's painter to 

 prevent the bight from dropping into the 

 water and fouling the propeller. Test the 

 engine to make sure that it is running and 

 that the clutch 

 is workin g 

 properly, and 

 let go. Allow 

 the boat to 

 drop back from 

 the mooring 

 enough to 

 allow you to 

 clear it and 

 then start 

 ahead, taking 

 care that you 

 do not veer off 

 so sharply that 

 the stern of the 

 boat will foul 

 in passing the 

 buoy or dock. 



"The Rules 

 of the Road" 

 are published 

 in booklet form by the Steam Boat Inspec- 

 tion Service and give complete instructions 

 as to the proper equipment for motor-boats 

 of various sizes. Four units, however, 

 should be included on every craft whether 

 large or small; they are, a good heavy- 

 anchor and at least 150 feet of good heavy 

 line to use with it; plenty of life preservers; 

 a good substantial whistle or fog horn and 

 the necessary lights to be used at night.

These lights are rigged as shown in Fig. 31. 

 The white light shows over an arc of 180 

 degrees while the starboard and port lights, 

 called side lights, show over an arc of 90 

 degrees. As will be noted from the draw- 

 ing, the starboard or right-hand light when 

 facing forward is green, while the port or 

 left-hand light is red. 



Before completing this series of articles 

 the writer wishes to call the attention of 

 every motor-boat operator to the necessity 

 of being courteous on the water as well as on 

 the land. When, passing a boat load of 

 timid women and children slow your boat 

 down rather than cause the wave from your 

 wake to fright- 

 en them or 

 maybe capsize 

 them. When 

 you see another 

 boat in trouble 

 run over to 

 them and offer 

 a tow, or at 

 any rate ascer- 

 tain whether 

 they would like 

 to have you 

 send help out 

 to them. Re- 

 member that it

 a cent to be

the compliment returned, 

 of your engine. A little extra care and 

 attention when laying ft up for the winter 

 or even when it is to be out of commission 

 only a few weeks or days will prevent a 

 variety of troubles later on. Investigate 

 pecular noises. They invariably mean that 

 something is out of gear. Ascertain the 

 cause and remove the trouble before the 

 engine is laid away.

Buoys have been called the sign posts of the waterways and there is probably no definition 

 which could state their purpose more clearly. The color designates the course of travel
